Transmission security (TRANSEC) is the component of communications security that results from the application of measures designed to protect transmissions from interception and exploitation by means other than cryptanalysis. Goals of transmission security include:
As in IPv4, subnetting in IPv6 is based on the concepts of variable-length subnet masking (VLSM) and the Classless Inter-Domain Routing methodology. It is used to route traffic between the global allocation spaces and within customer networks between subnets and the Internet at large.
From an avoided double redirect: This is a redirect from an alternative title or related topic of Variable-length subnet mask, another redirect to the same title.Because double redirects are disallowed, both pages currently point to Classless Inter-Domain Routing#VLSM.

SMTPS (Simple Mail Transfer Protocol Secure) is a method for securing the SMTP using transport layer security.It is intended to provide authentication of the communication partners, as well as data integrity and confidentiality.
A major difference between a DMZ or demilitarized zone and a network enclave is a DMZ allows inbound and outbound traffic access, where firewall boundaries are traversed. In an enclave, firewall boundaries are not traversed. Enclave protection tools can be used to provide protection within specific security domains.
Security is achieved by responding only to first hop packets, though other mechanisms are provided to reinforce this, particularly against local attacks. The election process is made orderly through the use of skew time , derived from a router's priority, and used to reduce the chance of the thundering herd problem occurring during the election.
OSPF is a layer 3 protocol. If a layer 2 switch is between the two devices running OSPF, one side may negotiate a speed different from the other side. This can create an asymmetric routing on the link (Router 1 to Router 2 could cost '1' and the return path could cost '10'), which may lead to unintended consequences.
